Overview

The PA wrist radiograph evaluates carpal bones distal radius and ulna for fractures and degenerative change. The patient places the palm flat on the detector with the wrist in neutral. This view is the foundation for wrist imaging and guides further projections.

Technique

Center the detector to the mid carpal region and ensure the wrist is flat without rotation. Use appropriate collimation to include the distal forearm and proximal metacarpals. Immobilize the hand to reduce motion artifact.

Clinical Indications

PA wrist is indicated for trauma pain and suspected scaphoid or distal radius fractures. It assesses carpal alignment and joint space narrowing. Additional oblique and lateral views complement the PA projection.

Image Assessment

Inspect cortical margins for fracture lines and evaluate carpal spacing and alignment. Look for signs of scapholunate dissociation and degenerative changes. Recommend targeted views or CT for occult injuries.
